Smart litter boxes promise to make cat care easier by automating cleaning and controlling odor. Two of the most talked-about models are the Smarty Pear Leo’s Loo Too and the CATLINK Ultra AI Self-Cleaning Litter Box. Both claim to simplify your routine while keeping your home cleaner and fresher. Here’s how they compare, based solely on their product descriptions and verified customer reviews.
Setup and Design
The product description for Leo’s Loo Too explains that it automatically detects when a cat finishes using the box, then sifts and deposits waste into a drawer. Reviewers described setup as straightforward. One reviewer wrote that both of their cats “took to it right away,” and another mentioned liking the “paw silicone pad” that makes it easy for cats to step inside.
According to the product description, the CATLINK Ultra AI includes a 65-liter internal space, a ComfortPlus silicone mat designed for comfort and to reduce litter tracking, and a large 13-liter waste container. Reviewers confirmed that setup was simple and quick, and several described the design as “sleek” and easy for multiple cats to use.
Cleaning and Odor Control
The product description for Leo’s Loo Too states that the box includes carbon filters and an EPA-certified odor control system. It also cites a 2024 survey indicating that “100% of users agree” the product helps control odor. Reviewers supported this claim, saying their homes “had no noticeable odor,” even with multiple cats. One reviewer noted that cleaning the drum monthly “prevented buildup” and kept it fresh.
The product description for CATLINK Ultra AI details a five-stage deodorization system that includes a C70 odor eliminator and premium HDPE waste bags. It reports an odor removal efficiency of 98.55%, verified by independent lab testing. Reviewers generally confirmed this performance, saying the litter box “kept the house smelling clean.” No reviewers reported persistent odor problems.
Smart Features and App Experience
The product description for Leo’s Loo Too highlights an app that tracks a cat’s weight, logs visits, and enables custom settings and remote cleaning. It also supports voice control via Alexa or Google Assistant. Reviewers described the app as “full-featured” and said they enjoyed monitoring their cats’ activity.
In contrast, the CATLINK Ultra AI includes more extensive features. Its product description states that it offers AI camera integration, two-way audio, and real-time live streaming. It also tracks the health of multiple cats and provides daily and weekly reports through its app. Reviewers appreciated these smart features and noted that the app provided “health updates” and reminders. One review mentioned that the app allows only one person to log in at a time, which they found inconvenient.
Noise Level and Operation
The Leo’s Loo Too product description specifies a noise level of 30 decibels during cleaning, describing it as “whisper-quiet.” Multiple reviewers supported this, stating that the litter box operates so quietly they “barely notice it running.”
The CATLINK Ultra AI product description does not include a specific noise measurement. However, it mentions that its motor runs quietly, and reviewers described it as calm and “non-startling” for their cats. Both product descriptions note built-in safety systems that stop operation if a cat approaches.
Maintenance and Support
The product description for Leo’s Loo Too does not include details about maintenance costs. However, reviewers frequently mentioned changing the liner weekly and cleaning the drum monthly. One reviewer who encountered a technical issue said customer support was responsive and resolved the issue quickly, noting that the replacement part was covered under warranty.
The CATLINK Ultra AI product description states that the 13-liter waste container can go up to 20 days without emptying for one cat and that included waste bags can last up to 1,000 days for a single-cat household. Reviewers confirmed that maintenance was simple and infrequent. One reviewer described an issue with waste sticking to the box, which required more frequent cleaning, but this was not a common complaint among the other reviews.
Safety and Build Quality
Both product descriptions emphasize safety. The Leo’s Loo Too includes radar and sensor-based safety systems, and reviewers reported that their cats adjusted comfortably. One reviewer specifically mentioned appreciating the “chew-proof cord” as a thoughtful design feature.
The CATLINK Ultra AI product description lists ten levels of protection, including anti-pinch sensors and radar detection. It also cautions against placing the unit on carpets to prevent sensor interference. Reviewers described the build as sturdy and the materials as “high-quality.” No reviewers mentioned safety concerns.
Final Thoughts
Based on the product descriptions and verified customer feedback, both litter boxes perform well but cater to slightly different preferences.
The Smarty Pear Leo’s Loo Too focuses on quiet operation, dependable cleaning, and a well-designed app that helps monitor your cat’s habits. Reviewers consistently praised its odor control and the responsiveness of customer service.
The CATLINK Ultra AI offers a more advanced experience, with camera monitoring, two-way audio, and detailed health tracking for multiple cats. Reviewers appreciated its ease of use and odor control but mentioned a few small drawbacks such as the single-user app limitation.
If you value simplicity, quiet operation, and strong customer support, the Leo’s Loo Too is an appealing choice. If you prefer advanced monitoring and AI-powered features, the CATLINK Ultra AI offers more technology at a slightly lower price.
